For five years Merlin has been in out heart and now it's coming to an end, but if you aren't ready to say goodbye, if you feel that there's a lot more of the story to be told, then sign this petition and let the BBC and the Merlin writers and producer know about it. The show has had strong consistent ratings and many shows have been renewed because of fan demand so please help fellow Merlin fans and sign, it won't take but a moment.
